- Hydrothermal Synthesis of Monodispersed BaGdF5:Yb/Er Nanoparticles for CT and MR Imaging
Rongjin Sun, Ting Yin, Peng Huang, Guo Gao, Joseph George Shapter, Yulan Shen, Jingjing Zhang and Daxiang Cui

Upconversion nanoparticles have the promising application as contrast agent for computed tomography (CT) and magnetic resonance (MR) imaging. In this contribution, a facile one-pot hydrothermal method has been developed for synthesis of monodispersed BaGdF5:Yb/Er nanoparticles (20-25 nm). In vitro and in vivo imaging results demonstrated the synthesized BaGdF5:Yb/Er nanoparticles can serve as effective contrast agents for CT and MR imaging.
- A Novel High Efficient Catalyst AgBr/CaMoO4 for the Reduction of p-Nitrophenol
Xiaomin Wang, Jimei Song, Rui Gao and Jie Yang

The composite catalyst AgBr/CaMoO4 displaying a higher catalytic activity. The conversion efficiency of 4-NP to 4-AP with AgBr/CaMoO4-5% as catalyst could reach 100% within only 4 min, which might be attributed to more available active sites from the highly well-dispersed AgBr nanoparticles on the surface of microspheres CaMoO4.
- Mechanistic Chemistry of Extraordinary Capacity of Salvianolic Acid B on Oxidatively-damaged Mesenchymal Stem Cells
Tingting Wang, Xican Li, Yunrong Li, Jianrun Wu, Yuyin Huang, Gang Wei and Dongfeng Chen
Version of Record online: 11 OCT 2016 | DOI: 10.1002/jccs.201600112
Salvianolic acid B can not only protect mesenchymal stem cells against oxidative damages but also promote their proliferation. The mechanisms of protective effect possibly include Fe2+ chelating, and direct radical scavenging which is involved in electron transfer and hydrogen atom transfer pathways. Its proliferation-promoting effect may be attributed to the carboxylic group, ester group, or benzofuran ring.
- Electrochemical Behavior of Polypyrrole-modified SnS2 for Use as Anode Material in Lithium-Ion Batteries
Dawei Luo, Feng Lin, Wangdong Xiao, Zhijun Li, Chaoyun Luo and Xue Li
Version of Record online: 10 OCT 2016 | DOI: 10.1002/jccs.201500491
SnS2 nanoparticles were self-assembled into a uniform 3D flower-like nanostructure, which consisted of a number of 2D nanosheets. In the case of SnS2 modified by polypyrrole (PPy), the image shows that the entire surface of SnS2 is coated with many PPy nanoparticles of size of 50 nm. The electrical conductivity of SnS2/PPy is much higher than that of SnS2.
- A Facile and Efficient Synthesis of 4-Arylidene-2-phenyl-5(4H)-oxazolones and Their Antimicrobial Evaluation against Selected Human and Phytopathogens
Christopher Voosala, Padma Suhasini Kilaru and Uday Kumar Dasari
Version of Record online: 10 OCT 2016 | DOI: 10.1002/jccs.201600083
A series of 5-(4H)-oxazolones have been synthesized via both conventional and microwave-assisted methods in the presence of calcium acetate and 4 Å zeolites. The title compounds were evaluated for their antimicrobial properties against selected human and phytopathogens.
